Probability Questions & Answers

What would be the experimental probabililty of the coin landing on heads if it is ossed 50 times, and it lands on heads 28 times?
The correct answer is 14/25. The proportion of heads in this experiment will be equal to the total number of favorable events (i.e. heads) divided by the total number of events (i.e. heads+tails). By this formula, we shall get : 28/ (28 + 22) = 28/5
What is the probability of picking a green marble, then a green marble if you do not put back the first marble?
The correct answer is 3/95. The probability of picking a green ball marble at first is 4/20 (total number of green marbles/ total number of marbles present). Since the first green marble is not returned, the probability of picking another green marbl
What is the probability of picking a green marble, then a blue marble if you do not put back the first marble in a jar full of 6 red, 4graan, 5 blue, 5 yellow marbles?...
1/19Find the probability of picking green (4/20), then find the probability of picking blue (5/19). Remember there is one less marble in the jar. Finally multiply the probabilities and reduce to get 1/19
What is the probability that on a math test 5 out of 30 students got an A all three got an A on the test if three students are chosen at random without replacement?
The correct answer is option 1/406. To find the probability of 3 students got an A on a test, multiple the probabilities of the 3 students. Probability of the first student = 5/30 = 1/6 Probability of the second student = 4/29 Probability of the thi
